Notes
6.1
If
test
solutions
other
than
those
described
herein
are
to
be
used,
then
the
solutions
should
be
agreed
upon
between
the
vendor
and
customer
prior
to
testing.
6.2
The
three
solutions
being
used
to
perform
this
test
exhibit
some
potential
for
health
and
safety
hazards.
Safety
precautions
shall
be
observed.
6.3
It
is
the
intent
of
this
test
method
to
subject
a
different
set
of
test
samples
to
each
test
solutions.
It
is
at
the
option
of
the
tester
to
subject
the
samples
through
the
test
solutions
consecutively.
If
the
samples
fail
after
consecutive
solutions
the
test
should
be
performed
with
individual
test
solutions.
5.1.1
The
test
specimens
shall
be
submerged
for
a
mini¬
mum
of
3

shall
be
identified
by
mark¬
ing
with
a

pencil
or
equivalent
technique
which
is
not
removed
by
the

Preconditioning
5.3.1
Measure
and
record
nominal
thickness
of
the
test

using
IPC-TM-650,
Method
2.2.18.
5.3.2
Place
the
etched
specimens
vertically
in

metal
rack
and
dry
the
specimens
in
the
oven
for
60
±
5
minutes
at
105℃
[221

Air
flow
around
each
specimen
must
be
assured.

Remove
the
specimens
from

and
immedi¬
ately
place
in
the
desiccator
to
cool
for
60

The
test
shall
be
performed

5.5.2
Remove
the
specimens
individually
from
the
desicca¬
tor
and
weigh
to
the
nearest
milligram
on
the
analytical
bal¬
ance.
Samples
must
be
weighed
within
60
seconds
of
removal
from
the
desiccator.
Record
these
weights
as

5.5.3
Place
the
rack
into
the
beaker
of
solvent,
start
the
60
minute
timer
and
using
tongs
place
the
specimens
in
the
rack
at
suitable
intervals
(recommend
approximately
2
minutes).
Insure
that
the
specimens
are
completely
immersed.
5.5.4
Place
the
metal
clip
on
the
balance
and
tare
it
out.
5.5.5
After
10
minutes
+15,
-0
seconds,
using
the
tongs
remove
the
first
specimen
from
the
solvent
and
start
the
60
second
timer.
5.5.6
Slowly
wag
the
specimen
in
the
air.
As
soon
as
the
specimen
is
free
of
surface
wetness,
but
no
longer
than
30
seconds,
place
the
specimen
on
the
balance
supporting
it
on
the
metal
clip
such
that
both
surfaces
of
the
specimen
are
exposed
(placing
the
specimen
flat
on
the
balance
pan
is
not
permitted
since
evaporation
from
the
side
next
to
the
pan
will
be
reduced.)
